Version 1.06

• Optimized code and reduced binary size
• Fix: Available sketch size corrected (Corrects 'Not enough space' error at firmware flashing)

Version 1.05

• Experimental support for other devices ET-81W and Floureon HY08WE
• Reduced bin file size

Version 1.04

• Experimental support for other devices ET-81W (still for testing only). These devices has other temperature values and other schedules. Please report any unknown messages and which function on thermostat was selected. So far, following parameters are expected to work: deviceOn, temperature, targetTemperature, floorTemperature. Schedules will not work. Unclear functions, please report: Time synchronization, schedulesMode, ecoMode, locked

Version 1.03

• Fix: After setting schedules, the device sends now the whole schedules for confirmation.

Version 1.02

• MQTT: New option 'Send every property change in a single MQTT message'. If not selected (default), state will sent as a complete json - no difference like before. If selected, properties will sent in sepearate, single MQTT messages. For example: Changes on property 'deviceOn' will sent with topic '../properties/deviceOn' and payload 'true|false', if the option is selected.
• MQTT: Optional configurable state and set topics for MQTT: if not configured, for both cases topic 'things' is used - no difference like before
• MQTT messages are send now with 'retain' flag
• Added 'Running since: x minutes' at info page to check for firmware crashes
• Fix: Update of target temperature in manual mode will push a MQTT update right now
• Fix: Setting systemMode and fanMode

Version 1.01

• Time zone sync for offset of NTP-UTC-Time via internet is now optional. Alternatively a fixed offset in minutes can be stored.

Version 1.00

• Fix: ESP disconnected and was not reconnecting automaticly

Version 0.99

• Serveral fixes for webinterface (e.g. Upload in Chrome was not working)
• Fix schedules. ESP was hanging in endless loop in last 2 schedules of day

Version 0.98

• Webserver can't be disabled anymore to ensure that thermostat can configered all the time
• MQTT port can be configured now
• Serveral fixes for webinterface (Saved message, no timeout, clock settings)

Version 0.97

• Improved behavior for targetTemperature. If target is changed via MQTT/Webthing and thermostat is in 'auto mode', the thermotat switches in 'manual mode' now. Before only the target for 'manual mode' was changed, but had no effect when thermostat was in 'auto mode'
• Fix: targetTemperature gives correct actual value now, when in 'auto mode'

Version 0.96

• Supports Mozilla Webthings, properties like temperature, desiredTemperature, On/Off, manualMode are available in a fancy web interface which can control the device outside your home network also. MQTT still supports more properties.
• Device configuration via Web-Interface added for things like: Model, NTP-Server, Timezone API, Weekday offset
• Heating relay status supported. To make this work, a hardware modification is needed: 2x10kOhm resistors have to be soldered to IO 5 of the ESP. For detailed description with pictures, see here: klausahrenberg#17 (comment)
• ArduinoJson library removed, own json creation and parsing implemented
• ESPAsyncWebServer library removed because of memory issues
• Fix: Automatic reconnection after loss of network should work now

Version 0.95

• Fix: Buffer for time zone sync increased again to 1024. Length of "http://worldtimeapi.org/api/ip" response had increased because of new parameters

Version 0.94

• Fix: Schedule temperature can now set in 0.5 steps

Version 0.93

• Fix: Property "systemMode": Changing of cooling mode at the device should trigger an mqtt message now.
• Fix: Property "schedules": Changing of schedules at device should trigger mqtt messages now.

Version 0.92

• Fix: Property "systemMode" corrected

Version 0.91

• Property "systemMode" for model BAC-002-ALW added; possible values: "cooling"|"heating"|"ventilation"
• Property "schedulesDayOffset" added (default: 0); details see description
• Property "thermostatModel" added; values "BHT-002-GBLW"|"BAC-002-ALW"; only readable. Model will be configered by the firmware based on the results of the MCU at device initialization
• Property "actualFloorTemperature" only in device state message included at model BHT-002-GBLW
• Property "fanSpeed" and "systemMode" only in device state message included at model BAC-002-ALW
• Removed some detail informations about the time sync from standard device state message. Details must be requered with a separate clock command
• Fix: schedules for model BAC-002-ALW should now read correctly out of the device
• Fix: wrong clock time zone calculation corrected, if DST was active

Version 0.9

• Fix: logMcu command is now working
• Fix: webService command is now working: README.md corrected to command 'webServer'. However, now are both words working.
• Fix: locked command is now working with payload false
• Fix: changing the webServer command does invoke a state update over mtqq now

Version 0.8

• Support for fan at some models with property "fanSpeed" wit states "auto"|"low"|"medium"|"high". If no fan is available at thermostat, "fanSpeed" will always stay at "none"
• With MQTT parameter "logMcu" true|false raw commands from MCU will forwarded to MQTT. By default disabled/false
• IP address added in json state message
• Fix: Devices with cooling/heating function do not sent actualTemperature, actualFloorTemperature and schedules at initialization - the result was, that never a device state was reported to MQTT because the information was incomplete. The state will be send now, even not all information are available yet

Version 0.7:

• increased JSON buffer in KaClock.cpp to prevent parsing failure
• definition of NTP_SERVER in ThermostatBecaWifi.ino to set a NTP server near by
• state request via mqtt
• state record includes now IP address of thermostat and if webServer is Running or not

Version 0.6

• initial version
